A CO2 sensor is a device that measures the CO2 concentration in the air. Carbon dioxide is a colorless and odorless gas, but it is the primary byproduct of human respiration. In enclosed indoor environments, the carbon dioxide produced by human breathing accumulates continuously, leading to the deterioration of indoor air quality.

CO2 concentration is one of the key indicators for measuring indoor air quality. Generally, the CO2 concentration in indoor air should not exceed 1000ppm. When the CO2 concentration exceeds 1000ppm, people will experience symptoms such as dizziness, fatigue, and lack of concentration.

CO2 sensors can be used to monitor the CO2 concentration in indoor air. By monitoring the CO2 concentration, the deterioration of indoor air quality can be detected in a timely manner, and corresponding measures can be taken for improvement.

The main roles of CO2 sensors in improving indoor air quality are as follows:

● Warning Function: CO2 sensors can monitor CO2 concentration in indoor air in real-time and issue warning signals. When the CO2 concentration exceeds a set value, the sensor will trigger an alarm to remind people to pay attention to indoor air quality.

● Ventilation Control Function: CO2 sensors can be connected to ventilation systems to automatically control the ventilation volume based on the CO2 concentration in indoor air. When the CO2 concentration rises, the ventilation system will automatically increase the ventilation volume to reduce the CO2 concentration in the indoor air.

Using CO2 sensors for indoor air quality improvement offers the following advantages:

● High Accuracy: The measurement precision of CO2 sensors is high, which can accurately reflect the CO2 concentration in indoor air.

● Strong Real-time Performance: CO2 sensors can monitor the CO2 concentration in indoor air in real-time, providing assurance for taking timely measures.

● Low Cost: The price of CO2 sensors is relatively low, making them suitable for large-scale applications.

CO2 sensors have broad application prospects in the field of indoor air quality improvement. With the continuous development of CO2 sensor technology, their application will become more widespread, making greater contributions to improving indoor air quality.
